Sorry it took me so long to respond. The only place I've heard of eating chili over rice is Hawaii, but in my years there it was an absolute. there were little vans that served "plate lunch" of various kinds, and always with one-two-tree scoop rice. To this day a favorite way to eat chili is over rice in our house (and it always had beans). When you went to zippies, you were always asked how many scoops of rice you wanted with your chili. The rice at the plate lunch places was always a very starchy, short grain rice served from an old fashioned ice cream scoop. The meal might be chili or curry or kal bi ribs or beef stew .... you name it. I miss that most about Hawaii, the wonderful cosmopolitan foods we had.
